Title: Reinforced concrete structures for strong rooms - incorporating polypropylene fibres to modulate shock propagation
IPC: E05G1/024
Filed: 1974-07-29
Abstract: Concrete structures reinforced with a matrix of horizontal and vertical metal rods and with helically twisted strips of metallic mesh, where the matrix concrete is laid up in thoroughly consolidated layers which incorporate polypropylene fibres, is used in the construction of strong rooms, fortifications etc. at risk from mechanical, thermal or explosive assault. Presence of polypropylene fibres modifies the shockwave propagation characteristics of the concrete to better match the characteristics of the metal components, to reduce the risk of out-of-phase shock propagation generating sufficient interfacial tension to separate the components and induce large scale cracking.

Title: Injection moulding mechanism for nozzle - has needle valves operated from outside ensuring smooth surfaces at injection points
IPC: B29C45/27
Filed: 1979-06-12
Abstract: The needle valves serving in an injection nozzle mechanism having a directly or indirectly heated nozzle, are operated by a plunger assembled in the heating channel block which is bolted to the moulding cavity plate for controlling the flow of the molten synthetic material from the plasticiser into the mould. The needle valves are opened inwards by the pressure of the molten material during injection, against the friction of the movable parts, and they are moved axially in the bores of an injection nozzle enclosed by the heating channel block. The injection nozzle has one or more bottom outlets which are sepd. from the adjacent recesses in the mould cavity plate by an air gap. During operation this is filled by the molten synthetic being worked and the needle valves project through it so that when injection is finished, the openings in the moulding plate leading into the moulding cavity can be closed. The needle valves assembled in one injection nozzle are operated by one plunger, so that with a single particular nozzle, a number of prods. can be injected, or one large prod. can be injected at a number of points. After injection the inlets can be closed by the needle valves, so that the inner wall of the mould presents a smooth surface at the points of injection. The pitch of the needle valves is kept very small the min. being 3mm. The operation of sets of needle valves by one plunger makes for a compact, accurately produced combination. The needle valves are controlled from outside and can be positioned as desired without any dismantling.

Patent PT-74487-A (PT)
Title: Process for preparing spray dried base beads and detergent
IPC: C11D7/00
Filed: 1982-02-25
Abstract: Free flowing spray dried beads which are useful as a detergent or for the manufacture of a particulate built synthetic nonionic organic detergent composition include water softening aluminosilicate (such as a zeolite), bentonite and water soluble builder, and may also include water soluble synthetic organic detergent and a small proportion of water soluble silicate, although such silicate is preferably omitted. The beads can be made to be of a bulk density within a broad range, and the bulk density may be varied by control of the bead formula and by modification of spray drying conditions. The base beads and detergent compositions formulated with them are of reduced aluminosilicate deposition characteristics, due to the presence of bentonite and the absence of or presence of only a low content of water soluble silicate, with the bead composition being maintained within given ranges. The moisture content of the beads will be such as to maintain at least 2% and preferably 3% or 4% or more of moisture in the bentonite so that its normal swelling power is retained, because the swelling of the bentonite is considered to be important in dispersing the beads in wash water and also, even more importantly, in helping to prevent aluminosilicate agglomeration and objectionable deposition thereof on materials washed, and in helping to break up any minor proportion of such agglomerates which might be formed.
